Obtain increased wheel travel and mild lift height with this heavy duty Upper Control Arm system. The tubular Upper Control Arms feature 1.25 OD. .120 wall thick chromoly tube construction with 1 diameter Stainless Steel Uniballs that attach to the factory spindle without drilling. These heavy duty UCAs have been designed to work in conjunction with Fabtechs legendary Dirt Logic 2.5 Coilover shocks for a complete front suspension system upgrade. The F150s offroad suspension performance will be greatly enhanced due to the extensive ride tuning of the stainless steel Dirt Logic 2.5 Coilovers and rear Dirt Logic 2.25s.

The factory GM upper control arms are replaced with Fabtech’s Uniball Upper Control Arms that provide additional wheel travel with an extra degree of caster compared to stock UCA’s. They are constructed of the finest material with .120" wall 1.50" OD 4130 Chromoly tubing. High quality 1" FK Stainless PTFE lined Uniball bearings are utilized in place of ball joints. These super stout Control Arms are designed for increased longevity in rugged offroad conditions while providing a more positive on road feel.

Fabtech offers their top of the line Dirt Logic 2.25 shocks with this quality 2500HD lift kit. They are constructed with a stainless steel body and a NitroSteel® piston rod for maximum corrosion resistance and durability. The front shocks comes with remote aluminum reservoirs to help cool the shock oil for more consistent damping in rugged terrain. These high quality Dirt Logic shocks will provide a superior ride quality both on and offroad with excellent damping for offroad use.

This high quality GM 2500HD lift kit offers an increased ride height for enthusiasts looking to run a 35" tall tire with enhanced offroad capabilities. The stance of the vehicle will become more level front to rear for an aggressive look.
